Apple Watch Could Detect Sleep Apnea, High Blood Pressure

The University of California San Francisco and Health startup Cardiogram have partnered together on another study aiming to provide details on just how well the Apple Watch is able to detect common health problems.

The USCF team and Cardiogram trained the AI-based algorithms to detect the two conditions based on the principles that patients with low heart rates are more likely to be diagnosed with high blood pressure also known as hypertension., while those with a certain beat-to-beat rate variability are very likely wot be diagnosed with sleep apnea.

The study, shared today at the American Heart Association meeting in Anaheim, reveals that the Apple Watch is capable of detecting sleep apnea with 90 percent accuracy and hypertension with 82 percent accuracy.

Sleep apnea affects an estimated 22 million adults in the USA, with another 80 percent of cases of moderate and severe obstructive sleep apnea undiagnosed, according to the American Sleep Apnea Association. These patterns, according to Cardiogram and UCSF, are invisible to the naked eye.

Cardiogram has been looking into the potential of heart rate sensors on wearable devices for a while now, and thus far the results of its studies have come off as a way to measure how good a certain device's sensor or software is, like the Apple Watch atrial fibrillation detection.

According to Cardiogram, heart rate sensors can detect both conditions, because your body's autonomic nervous system connects your heart with the brain, stomach, esophagus, liver, intestines, pancreas and blood vessels. However, this study feels like a breakthrough for all wearables. It's incredibly exciting to see that the potential of wearables to let us know about unsafe health conditions - non-invasively - is alive and well, but this also requires the companies in charge of these platforms to deliver on software and AI as good as DeepHeart.
